Application January 16, 1943, fieri alltle; 413557 .8 Claims. tel. 12414) I This invention relates to lasting machines, vanil is herein illustrated as applied to a machine con structed generally as disclosed in United States Letters Patent No.2, 324,5.09,',g'1janted on July 20, 1943, on an application'of mine, which maehine it'isan objectof the ihvent'ionto improve in certain respects, It is to be understood, however, that th invention is not limited in its applicabilityto thatparticular machine.

'1' In the machine shown in theaboye-nientioned y} Letters Patent a last having anu'ppera'nd an in- Isole thereon is positioned bottom upward by means adjustableiin directions heightwise of the last to determine variably in that respect the position o f the last. The margin of theupper about the toe end of the last is wiped inwardlypver the insole by wipers carried by a wiper supportwhich is moved upwardly to bring them into position for thus operating on the upper,' an d associa tedfwith the wipers on the wiper support is a substantially U-shap'ed flexible toelformer arranged to embrace the upper around the toeend of the last .andto wipe it heightwise of the la'stin response to the up} ward'movement of the support. The wiper support is thus moved upwardly by fluid operatfed Letters Patent as inedified ,for purposes of the means, and its upward movement "'is limited by stop mechanismwl ich thereafter confines the wipers to movements in a plane in wiping the margin of the upper inwardly over the insole.

The construction above described has beenused 1.,

with very good results under various conditions. An object of this invention, however, is to obtain still better results, especially when the bottom of the toe end, of the lasthas a pronounced convex :curvature. Forthe purpose in view the construction herein shown is such that after the wiper support has been mo ved upwardly to carry the wipersinto-position for wiping the margin of the upper inwardly' over the insole, it is fr ee to move still farther upwardly against the resistance of gravity alone in response to pressure of the mar- 'gin of the upper on the wipersinthe overwiping operation. This permits the wipers in their inwardmovements tofollow the convex curvature of the bottom of the last without increase of pres;-

sureon t mar in f .t eun an s i slv permits the machine to beiiso adjusted that the wipers apply to the upperiat the extreme edgegoi the shoe bottom greater wiping pressure than would otherwise be practicable. It also prevents the wipers from acting with too much force on'the g e ed m r n f th urpe e a dis an e m the edge of the shoebottor'n especially if the upper is comparatively thick. Freedom for such fur- -ther upward movement of the wiper support is they eccupywhen the iwipers' 'are at a fo ded in te a e sfi ti sh n P .ei z s w ns-912 9 b t en t ri m mbe s i ni fieat n 'e .var i li fil 1 9W beware ease larly described withreference to the accompany- ,n grates ,eridlith ee t p ted 61 the claims.

As-in-themachine shown and described in the .previously mentioned-"Letters Patent; haweis'truotidn herein shown incl'udes 'a' shoeposit'ioning devi ce 2 against which the shoe is fi :by the operator bottom upward; this dev e bented ing -provided.-with a plurality" of rtii'gfigfa to extendthrough holeshin the tde end of the insole into 'holesin the-bottom of the last and with a plate 6 arranged *wengage the bottoi'rfface .of the insole todeterniinetheosition of I l4 (Fig. 4.) which are mounted for swinging.

erated to wipe the mar in of the upper inwardly over the insole the casting 24 and the parts supported thereon are free to move farther upwardly against the resistance of gravity in response to pressure of the 'margin of the upper on the wipers by reason of the slots 44 in the links 40, as illustrated in Fig. 2. This permits the wipers to follow the convex curvature of the bottom of the toe end of the last, when the last has such a curvature, and therefore permits the shoe-positioning device 2 to be so adjusted as movements along guideways on a wiper carrier I6 about the axis of a pin I8 (Fig. 6) on the carrier to close the wipers inwardly over. the shoe, Q

bottom widthwise of the shoeasthewiper carrier is operated to advance them lengthwise of the shoe. Such operative movement is-impartedto the wiper carrier by a fluid operated piston'2fl connected to the carrier by a piston'r'od 22'.

Wiper-closing movements are imparted to the wiper holders l4 in responsefto the movement of vw p a ri lengthwise'oi th'efshoe by mechanism not herein shown detail .but fully disclosed in the previously mentioned Iiet'ters Patent. The wiper'carrier [6' and its operating means are supported by afcasting 24,, whi'cli may'be termed a wiper support, and. this Toasting is supported on parallel links 25 and 2 8 for upward and downward movements? It is moved upwardly :to carry the wipers J2 intoposition for wiping the margin'of the upperihwardly over the insole by a pairof fluid-operated pistons .30 vefrti cally movable incylinders '32 secured to a portion "of the frame of the machine'and' in response to such upward movement ofthe casti ng 24 a substantially .U-shap ed'i flexible toe Iformer. 34,

supported by the casting as hereinafter described, wipes the upper around the toe end of the last heightwise. of the last preparatory to the wiping Iof its margininwardly over the insolebythe wipers .l2. As thus fardescribed theeonstruction herein shown is' substantiallylike that disclosed in the previously mentioned Letters Patent.

The upward movement of the wipe resupportn li h b e i eil r iei by stops into engagement with which it was carried, and accordingly the wipers l 2 .hav e been confined to movements in a plane in wipingthe marginof the upper inwardly over theinsole. For purposes of this invention such stops arev dispensed with and stop mechanism is provided instead for limiting directly the upwardmovements of the pistons This stop mechanismcomprises a pin 36 carried by each piston and extending throughslots 38 in the corresponding cylinder 32, the pin being arranged to engage the cylinder at the upper ends of the slots, toestop the upwardmovernent of the piston. :The pistons 30 are connected to the wiper-supporting ,casting 2-4 by links 40 pivotally mounted on; pins 42 in the casting and provided attheir lower ends with slots 44 (Fig. 2) through which extend .pins 46 mounted in upwardextensions. of: thepistons.

During the upward movements ofthei pistons 30 I h Pins 46 engagefihelinks at thel upperends of the slots 44 for raising the castin and the wipers to the position determinedby. engagement of the pins 36 withthe cylinders. .32 .at theupper movements in a plane. Since the casting 24 and the parts thereon are thus upwardly movable "against the resistance of gravity alone, there is no increase of pressure of the wipers on the upper during their inward movements by reason of the curvature of the bottom of the last. The provision for upward movement of the wipers also prevents them from acting too severely on the portions of the margin of the upper around the end of the toe where gathers or folds are most likely to form in the overwiping operation. Since the weight of the casting 24 and the parts there'- on is substantial, the machine is further provided with means for partially counterbalancing this weight, in order to prevent the wipers, in operating on some kinds of upper" materials, from applying too much pressure to the margin of the upper. This means comprises springs 48 seated on the heads of screws 50 which are threaded in the pistons 30 and bearing at their upper ends on lugs 52 extending forwardly from the upper ends of the link 40. The springs are held in place'by pins 54 extending upwardly fromthe screws 50 and by pins 56 extending downwardly from the lugs 52. Associated also with the pistons 30 are springs 58 which are compressed by the upward movements of the pistons and act through the pistons on the casting 24 to in?- crease the downward pressure of the wipers on the overwiped margin of the upper when the pistons are released from the pressure of the op erating fluid in the cylinders 32, as they are-at a predetermined time in the operation of the machine. The springs 58 are seated at their lower ends on enlarged end portions 60 of the pins 36, and bear at their'upper ends on washends of the slots 38. The wipers are thusmoved upwardly into positionfor wiping the margin of the upper inwardly over-theinsole, the proper relation between thewipers and the shoe when thewipers are in this position being determined lby vertical adjustment of the shoe-positioning.. "device 2. When the wipers are thereafter 0pers 62 confined by nuts 64 on rods 66 which extend downwardly through the springs and through openings in the end portions 60, the rods being threaded at their lower ends in bars 68 secured in fixed relation to the cylinders 32. J

The substantially U-shaped flexible toe former 34, previously referred to 'as also movable upwardly by the wiper-supporting casting 24'zt0 wipe the upper heightwi'se of the last, preferably comprises a band of molded hard leather to the outer face of which is riveted a thin steelplate 10 (Figs. 5 and 6). Underlying this plate and the intermediate portion of} the leather band is a small plate 12 mounted on the upper end of-a stud 14 which extends upwardlyfrom ablock 16 resting on plane upper faces of the wiper holders [4. The block is provided with flanges 18 extending laterally and forwardly therefrom and also resting on the upper faces of the wiper holders, and it maybe moved alongthese faces with the toe former in directions lengthwise of movable inza: bore:l2-. l?ig inzthe nistcnzrold 2 lo, 84,;thereinz-thzrou h and a 1,S.(ZTWJ;.B8.. mounted of ;the::screw zbeing. .1311: ran ed .tozhold the .plate in propercadi s ejdnre- .lation ,to .the istud. lt will .beeevident ,thatthe plate .12, on which-the intermediate? po ti n of the toe former rests; permits thatpqrtionpfzthe .-t o e 'formerto bev movederelatively. to its supportving block .116 in; any. directionjn :a plane parallel tothe Wipers-12.1 '2 i t l y mountedmidway betwe n; ts opn e site ends onzthe ,stud-,1I.4 -;-i s ;a .crossbar -.90 ,;and pivotallyconnected-to 1the ends of ithis crossbar :are forwardly.-extendinglinksr92 pivotally con,-
